Nodal Planes

Postby Shannon Asay 1C » Sat Oct 19, 2019 11:26 pm

What are nodal planes exactly and why do the s- orbitals not have them?

Nodal plane means that the wave function = 0, meaning that the probability of finding electrons in that plane is zero. I am not sure about why s-orbitals don't have nodal plane, but I think that it is because there is no node when depicting the math model of the s-orbital.

In the s-orbital, electorns have no angular momentum (l = 0), so they're distributed around the nucleus instead of circulating it. In p-,d-, and f- orbitals, electrons have angular momentum (l>0), and the spherical movement creates nodal planes.

Nodal planes are planes in the p, d, and f orbitals with zero electron density probability. In other words, there is no likelihood of finding an electron in that spot.

Because of the shape of s orbitals, it is impossible for them to have nodal planes. This is unlike p, d, and f orbitals.

S-orbitals have electrons that are distributed spherically symmetrical around the nucleus so while they do not have any nodal planes, the s-orbital does have radial nodes. The 1s orbital would not have any nodes, but the 2s orbital would have one node, the 3s orbital would have two nodes, etc.

In an orbitals, nodes are non-spherical regions where the electron cannot exist. This can be a nodal plane or nodal cone. The s- orbitals do not have a nodal plane because the entire orbital is the same phase.
